Calibration and Screen Integration
Point-by-point calibration adjusts brightness and chromaticity across the display. Offset-based mapping supports freeform layouts, including spherical and diamond-shaped screens. The specification also lists dual receiving-card, loop and dual-machine backup; these functions require an appropriately designed system.
Temperature, humidity and smoke monitoring are available in conjunction with a multifunction card. These are system functions and should not be treated as built-in sensors on the receiving card.

Frequently Asked Questions
What is the loading capacity of the Colorlight i5A-905?
The V6.1 specification lists 256 × 256 pixels for full-color loading and calibration. Its separate special-application column limit does not mean a 1024 × 1024-pixel loading area.
What power supply does the i5A-905 require?
The specified input range is DC 3.3–6 V, with a rated current of 0.6 A and power consumption of 3 W. Power can be supplied through a wire terminal or the HUB board.
Which LED module scan modes are supported?
The card supports static operation through 1/32 scan. Check the module driver IC, scan mode and HUB wiring before selecting it as a replacement.
Does the i5A-905 support brightness and color calibration?
Yes. It supports point-by-point brightness and chromaticity calibration over a 256 × 256-pixel area.
Can the i5A-905 monitor cabinet temperature and humidity?
The specification lists monitoring in conjunction with a multifunction card. Additional system hardware is required; the receiving card alone should not be assumed to contain these sensors.
